Abstract
A rotating lens antenna seeker-head provides conical scan capability for an ntenna system while simultaneously providing a two axis scan capability by positioning rotating lens in front of a microwave antenna. A pair of rotatable lens are disposed in parallel across the beam front of the antenna system to refract the microwave beam away from the antenna boresight, providing variable scanning modes. The third wedge provides the conical scan pattern for the antenna regardless of the position of the two axis wedges.
